Refer to the table to determine the minimum wire gauge for a single sensor system (one
transmitter and one receiver). The distances specified are between the power source and the
last (farthest) unit on the single wire run. For multiple detector configurations, divide the wire
distance in the table by the number of systems in the configuration (1 system = 1 transmitter
and 1 receiver).
This table does not include wiring gauge requirements for optional heaters.
Refer to the graphics below for wiring routes examples. The illustrations depict both one, and
two sets of detector systems on a single wire run.
The graphics below show simple examples of wiring concepts, depicting how to power the
transmitter and receiver pairs, and how to combine alarm outputs. Local regulatory
requirements and technical parameters specific to a connected control panel determine the
exact details of the wiring. Review local regulations and the connected control panels
technical documentation before planning wire routes and connections. Selecting the proper
wire routes and gauges depend on the number of devices, overall distance, and voltage drop
parameters for each individual device.
